Groton, in the coumy oi liliddlc f State of lvlossochosetts, have 121- Ufii. tein Improvements in Robbers-rolled Shoes and Methods of Melting the Some oi w the following description, in connectim with the accompanying drawings, is a specification, like reference characters on. the drawings incliceti ig like in the several figures.

This invention relates to the manufacture of rubber soled shoes and more particularly to a novel method of making robber soled shoes of the type having a. com cs iii-simila r'textile upper and e v dcenizeble oh her sole bottom and. to e novel eru ohe shoe of this type. These types soled shoes are generally sneakers and. according to "the pies commercial method' of momifimlm'e canvas upper and llllGltllOEiS rubber oot tooling materials oii'e secured together l1}; vulcanization. Although these sneakers supply the present demand for on inexpensive shoe adopted for summer weer they are unsatisfactory because of their weight and. clumsy appearance and the i ulobcr composition insoles sweet the feet, Forthcw more the attachment of the robber sole to the canvas upper is entirely dependent upon the durability of the vulcanization which is often faulty so that the shoe gives unsatisfactory service. Also the losing extending along the side of the upper adjacent the sole is objectionable as it adds appreciably to the cost oft the shoe and gives o'cluoracteristic sneaker appearance to the shoe The present invention has for its general object to improve the manufacture of m1hher soled shoes of this type whereby the shoes produced is a much move comfortable and more serviceable shoe than the present commercial rubber soled shoe and has at neeter and more stylish appearance since along are Lion ccririio portions of me oi Molten away to show its (:ol'ililiilC-i()11 ou volition accord of canvas or t assembled on insole com in order that it high degree of 2 out-sole to that sotisfec cdby the use of U i l oiiinjo: hoot not to the shoe "tory suits solfite' time The shoe o nsole iiich it has been suc--" le i of fibrous width of the fold may he suiiicieiit to allow" of the overloaded portion of the upper when applied to the slwe illust-iovted.
